BOOT AND SHOE SOLE BURNISHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 249,698, dated November '15, 1881,

To all whom @t may concern Be it known that I, CHARLES H. TRAsK, of Lynn, in the county ot' Essex and State of Massachusetts, have invented certain new and useful Improvements in Boot and Shoe Sole Edge Setting and Burnishing Machines, of which the following is a specification.

The objects of my invention are to provide. means or apparatus for imparting a reciprocating motion to the burnishin g device, which motion may be varied or adjusted as to its movement horizontally, and a further object is to provide mechanism whereby the burnisher may be suspended vertically and have a reciprocating motion imparted to it, while it is free to be moved in every direction required by the various curves and angles of the edge ofthe sole of a boot or shoe, when the same is held in a jack of usual construction adapted to edge setting andpburnishin g machines and devices therefor; and it consists, lirst, in the construction of a reciprocating bar provided with adjustable pivotal bearings; and it further consists in the construction, combination, and arrangement of certain clamping deviceswith the reciprocating bar to secure thereto. one or more burnishers, and in a hollow operating-handle adapted to conduct gas downward through the same to a burner, which opens and closes the gas-inlet passage by horizontal movement thereof; and it further consists in a ball-and-socket joint having a beltpulley and eccentric journaled at or near the axial line thereof, and having a driving-belt passing through openings in said joint, and an operating-handle having a reciprocating bar pivoted at or near its central portion, and havits upper end connected with said eccentric and its lower end provided with one or more adjustable burnishers; and it further consists in the combination of a hollow pendent support and a hollow operating-handle united by a ball-and-socket joint having openings in its socket, and having a belt-pulley and eccentric journaled within the ball, at or near the axial line thereof, and of a driving-belt passing through the openings of the socket 5 and it further consists in the combination, with a tilting frame having an adjustable weight, of the hollow pendent support, ball-and-socket joint having a belt-pulley and eccentric jour- A Application tiled March 5, 1881.

naled therein, and hollow operating-handle provided with a reeiprocatingburnisher, and also in the combination, with the hollow pendent tube and hollow operating-handle united by the hall-and-socket joint, ot means of conducting gas to the burnishers through said tube and handle and by means of an adjustable burner, and in the details ot' construction, hereinafter more fully described, and particularly set forth in the several claims.y

Figure l represents a side elevation of an edge setting or burnishing machine constructed according to my invention. Fig. 2 repre sents a top plan of the same. Fig. 3 represents an elevation of the burnishing device and connecting mechanism. Fig. 4 represents a vertical section oi' one moditication oi' the actuating mechanism of the burnisher andconnesting devices. Fig. 5 represents a similar view of actuating mechanism and connecting devices and modication of d rivin g-pulley Within ball-and-socket joint. Fig. 6 is a section view of pulley and joint at a right angle to that represented in Fig. 5. Fig. 7 represents a vertical section of the burnishin g devices and their attachment to the lower end of the reciprocatin g bar. Fig. 8 represents a detail view, showing the connection of the upper end ot' the actuatin g-bar with the concentric formed upon the pulley-journal.

A represents a horizontal belt for communieating power and motion to the shaft and pulleys B, supported by hangers from the ceiling overhead, which also sustain the horizontal tilting frame C, one end of which is provided with an extension-bar D, upon which is attached the adjustable counter-balance or weight E, which may be moved 'upon the said bar l) so as to nearly balance the opposite end or portion, F, with the horizontal beltGand pulleys H, which are journaled within the pivoted frame I, which is connected with the end ot' the bar F by a socket-joint, Y, provided with a pin and slot, so as to permit ahorizontal swingingmovement to be imparted to it in this direction and the journal of the pulleys H permits the vertical pipe K, connected at its upper end to said journal by a yoke-frame, X, to swing at right angles thereto, the pulley H being provided 'with a vertical belt, J, which extends downward cach side of the said pipe K and passes around within the plane of the axial line ofthe ball P and socket It. and is journaled immediately below said ball-and-socket joint, as shown in Fig. 4, t-he journal M thereof extending at one side of the pulley L sufficiently to form a y suitable bearing in the box Q, within which it revolves, heilig secured rigidly within the pulley L, its opposite end being formed with an eccentric, N, which revolves within the oblong slot or bifurcated end O of the vertical reciprocating bar S, which is vibrated upon the bolt or pivotT, passing through one of several holes formed in the same at or near the mid-length thereof and engaging within a corresponding hole formed in the case or handle U,which incloses the said reciprocating bar S, the lower end thereof projecting below the same and provided with key-bolts and pins for temporarily securing thereto the burnisher V, which is heated by a jet of gas from the burner W, which may be partially rotated horizontally so as to shut od' the same. The gas being introduced within the snpport-pipeKat aconvenientpoint above the ball-and-socketjoint, it is conducted around the same by means of the exible tube Y2, (shown in Fig. 3,) and enters the handle U and passes downward within the hollow space Z (shown in Figs. et and 5) to the burner.

It will be seen in Figs. 5 and 6 that the driving-pulley L is constructed within au opening formed within the ball P, which is enlarged sucientl y to receiveit and its journalliLwhich revolves within the axial line of said ball P and has bearings at each side of the said drivingpulley L, said journal M being provided with an eccentric, N, which actuates the vertical reciprocating-bar S, as described abo ve, the socket R, in this construction, being provided with suitable openings to permit the vertical belt J to pass freely, as shown in Fig. 6. By this latter construction the weight is more evenly distributed, and the friction of the journal and eccentric is reduced to the minimum, while the movement ofthe said handle and its burnishing devices in any and every direction required by the various curves and angles presented upon the edge of the sole and heel of a boot or shoe is free and unobstructed, and permits the same to be held in a jack, and turned or revolved, so as to quickly burnish and set the edge ofthe sole and heel of a boot or shoe by increasing or reducing the amount of pressure upon the burnisher, or the distance of its movements thereon, as the nature of the work may require.

The burnishersV and V are connected to the lower end of the reciprocating bar S by means of short projecting steadying-pins,which enter corresponding holes formed in the bearing-face of the burnishers, andare clamped firmly to the block 2 by screw-bolt 3 and thumb-nut 4 bearing upon a washer, as shown, the lower burnisher, V', being secured in a similar manner, the head of the screw-bolt 5 having a bearing thereon, and prevented from turning by a groove or hole formed therein, and adapted to slide upon the steadying-pin, as shown, this bolt passing through the block 2 and reciprocating bar S, and provided with a thumb-nut, 6, as shown clearly in Fig. 7.

It will be seen that when the two parts or members upon which the ball-and-socket joint P R is formed are brought into a vertical plane with each other the driving-pulley L, carrying the eccentric N, which actuates the reciprocating bar S, carrying the burnisher V, is revolving within the vertical plane of the said ball-and-socket joint, the bar may have a partial rotary movement horizontally,thusimpartinga reciprocating movement to the burnisher radiatingfrom orabout acommon center, or segment ot' a circle on a horizontal plane, or nearly so.

Having thus described my invention, what I claim isl. The reciprocating bar having an adjust able pivotal bearing and connected at its upper end with an eccentric, and having its lower end provided with a burnishin g device, as and for the purposes set forth. Y

2. The reciprocating bar pivoted at or near its central portion, and having its upper end connected with an eccentric, and having its lower end provided with the adjustable clamping devices described, whereby one or more burnishers may be secured thereto, substantially as and for the purposes sct forth.

3. The combination, with a ball-and-socket joint having a belt-pulley and eccentric journaled at or near the axial line thereof, of a reciprocating bar pivoted at or near its central portion and provided with one or more burnishers, substantially as described, as and for the purposes set forth.

4. In a burnishing-machine, a suspended ball-and-'socket joint having a belt-pulley and eccentric journaled at or near the axial line thereof, and provided with a hollow operatinghandle having a reciprocating bar connected at its upper end with said eccentric, and having its lower end provided with adjustable clamping devices adapted to secure thereto one or more burnishers, substantially as described, as and for the purposes set forth.

5. In a burnishing-machine, a pendent balland-socket joint havingabelt-pulley journaled within the ball at the axial line thereof, and provided with a gas-conductin g handle having a reciprocating bar pivoted therein, and having its lower end provided with adjustable burnishin g devices, substantially as described.

6. In a burnishing machine, a ball-andsocket joint having a belt-pulley and eccentric journaled ator near the axial line thereof, and having a driving-belt passing through openings in said joint, ,and an operating-handle supporting a reciprocating tool-holder, for the purposes set forth.
